SPECIFICATION forming part of Letters Patent No. 295,691, dated March,25, 1884-.

Application filed July 30, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY A. ToBEY, of Dayton, in the county of Montgomery and State of Ohio, have invented a new Improvement in WVatenCloset Valves; and I do hereby declare the following, when taken in conneotion with accompanying drawings and the letters of reference marked thereon, to be a l full, clear, and exact description of the same, I and which said drawings constitute part of this specification, and represent, iny I Figure 1, a vertical central section cutting through the outlet-passage from the. valvechamber; Fig. 2, a vertical section cutting at right angles to thesection of Fig. 1; Fig. 3, a transverse section below the valve and above the ounce; l l This inventiourelates to an improvement in that class of valves employed." for flushing l 2O water-closets, and in which a balance-valve is employed which. will suddenly open the flow to the bowl and automatically slowly close.

Valves of this class have been, made with a circular chamber, within which the valve is arranged, and into which chamber the water flows from the supply, with a concentric opening in the chamber, through which the water enters the passage to the bowl, the valve resting upon said concentric opening to close the 3O passage, and with asmall aperture through the valve from the water-chamber, so that the water from the supply will pass slowly from below the valve to its opposite'side, and, there counterbalancing the pressure of the water, will. force the valve to, and hold it i upon its seat, to close the passage to the bowl anduntil the pressure is removed from the opposite side, when the inflow of waterwill raise the valve to permit that inflow to pass to the bowl, butin such valves the inlet-passage has been at one side of the chambernear the valve, so that the pressureor momentum of the water is interrupted by the bend inthe column and prevents the direct anduniform action of the water, upon the entire exposed under side of the valve. Beingat one slide bf the chamber, theforce is necessarily greater atthe' point of entry than it is at other points around the face of the valve, and, as the column bends,it strikes the face ofthe valve at different angles. This irregular pressure is increased by the side pressure or reaction prohereinafter described.

ber.

valve, and causes the valve-to vibrate, pro-- ducing a disagreeable noise and uneven delivery. Again, in such inflowthat is to say, at substantially right angles to the axis of the valve-the waterin turning over into the conduced upon the sidesof the chamber and centric outlet flows irregularly into that passage. The break of the stream produced by the bend in-the passage into the chamber is the cause of this deflection of the water, and I such deflection causes an irregular action upon the valve, frequently deranging its operation, and requiring guides or other means than the valve itself to keep it in its proper relative position or to aid in its closing. l

The object of my invention is to overcome these difficulties; and it consists in a valvechamber having the inlet in axial line there with, with an outlet above the inlet, and an extension from that outlet upward into and concentric with said valve-chamber, so as to make the openingto the outlet and the valveseat thereon above the bend in the outlet-passage, and so as to form a clear concentric space in the valve-chamber below the valve-seat, combined with a free Valve in the chamber above the outlet-opening, and of substantially the same area as the chamber, whereby that portion of the under surface of the valve over the space between the outlet-passage and the walls of the chamber is exposed to the vertical or direct axial action of the water in the valveohamber, the construction of the valve and chamber being such as topermit a slight flow of water from thatpart of the chamber below the valve to that part of the chamber above, and an escape-passage from the chamber above the valve, and with a mechanism to open said passage above the valve, whereby the. water above the valve which produces the counter-balance upon the valve will freely escape and permitthe direct and axial action of the column of water below, as more fully A represents the case of thechamber B. This chamber has an inlet, Gfat its lower end, and substantially concentric with the cham- From the chamber a passage, D, leads to the bowl. This passage turns upward within the chamber, so as to form a concentric ,tube, or extension within said chamber. The upper end of this tube is open. This tubular extenloo sion E should have considerable length above the passage D, so; as to leave a concentric space between it and the wall of the chamber B, and this space of so much length and capacity as not to produce a break in the tubular column of water which surrounds the tubular extension or concentric passage F to F when. it, sets thereon. Thatportion of the the. valve.

ure inthe chamber is in the axial line of the.-

valve. outside the concentric passage stands over the space between the said passage and the wallv of the chamber B, and that portion of the valve is therefore exposed to the press ere. in. the chamber B. The. small passage b leads fromthatv part of the chamber B-below" the valve to the part of the. chamber above.v

It may be a'vertical groove in the periphery of' the valve, or a. vertical groove. in thewall of the chamber; or the valve itself may be slightly less in diameter than-the. chamber, so as topermit the. water to pass slowly through the space to that part of the chamber above The. infiow. ofwater to and presschamber. and valve, and because of the concentric. tubular extension Ethat column stands and. bears equally upon the valve at all points.

around-the, central passage. From that part ofthe, chamber above the valve an opening or passage, (Z, is made for the escape of water; but the area of the passage d must be much greater than the passage which permits the water in the chamber Bto pass from thatpart of the chamber B below the valve to that part of. the chamber above. If this passage d be closed. then the equilibrium produced upon the. valve will hold it in its closed position; but if. this passage cl be. suddenly opened to permit the water above the valve to. quickly escape, and thereby remove thepressure above the. valve, the pressure belowwill instantly raise. the valve, and the water will flow into the. opening F and down through the tubular extension into the.outlet.D.. Because of this tubular extension standing concentric with the, column of water and leaving the. water free. and. uninterrupted in its passage entirely around the chamber, the action upon the valve.

isequa'l at all points, and this, as. it. were, tubular column of water, rising, turnsfrom all directions and with equal force. and'pr'essure. over into the concentric. passage F, and prevents any possible deflection of the'valve or forming of vacuums in the chamber, which must, be the case where irregular or inter passage (1 for the escape of water from above the valve is that used in the Hartford Sanitary Plumbing Gompanys closet, and consists of a valve, 6, on a spindle, f, in substantially axial line with the tube that leads from above the valve G, and closes from the direction of the flow of water, so that the pressure of water tends to close the valve; and in connection with this valve-spindle is a bell-crank lever, h, upon which a float, H, is hung, which stands in a water-passage in connection with the bowl, and so that when the water stands at the predetermined level in the bowl the float will raise the lever h and draw the valve 0 onto its seat, as shown; but when the water is permitted to escape from the bowl, then the float H falls, and by its weight forces the valve 6 from its seat, so as to open the passage of escape from above the valve G, as seen in chamber below the valve, such perfect even-' ness of pressure upon the under side of the. valve is attained, and such an. equal escape from the chamber at all points into the outlet produced, that the valve requires no guide other than its own periphery upon the walls of the chamber.

I do not wish to be understood by the term concentric inlet toimply that the supplypipe must lead directly into the chamber B in a concentric direction. It may lead at right angles into a chamber below, which chamber, being. concentric with the chamber B above, forms the concentric inlet which I have here in described.

I claim The herein-described valve, consisting of the chamber B, having an inlet. 0, concentric therewith and below the outlet-passage,

the outlet-passage from one side of the chamber, with a tubular extension therefrom into said chamber and concentricv therewith, and so. as to form a concentric space bet-ween the walls of said chamber and said tubular extension, with the valve G arranged to. seat upon the open end'of said concentric extension, and of an area substantially equal to the internal, area of the chamber, but so as to leave aslight passage from that part of the chamber below to the part of the chamber above the valve,

and an opening from that partoflthe chamber above the valve, withmech'anism, substantially such as described, to open said passage above thevalve for the escape of water therefrom, substantially asdeseribed.
